Americans leave out the "u" in colour, armour, neighbour, etc. We no longer pronounce "night" as [ni:xt] or [ni:t] (IPA). We could come up with a huge number of examples, but why bother? Language evolves over time, words lose or gain meaning. It's a natural process. You'd think an academic institution would understand this simple concept, but I guess grabbing headlines is more important than practicing proper academia.
Emoticons are just an evolution of a new language. It's actually quite extraordinary. We have now created symbols that can represent simple meanings cross-culturally and cross-linguistically, and these symbols are popularized in large part by the youth of the world. They are creating a whole new language right before our eyes. I wouldn't be surprised if we would soon be able to communicate simple messages between different cultures that speak different languages via symbols (some would argue we already can). It's a shame that institutions such as this one and the "get off my damn lawn" crowd are ridiculing such an extraordinary example of the human ability to adapt and break down communicative barriers.
